But, today's kernel has a hard limit of 32. With increase in memory size, we are seeing the number of E820 entries reaching close to 32. Patch below bumps the number upto 128. The patch changes the location of EDDBUF in zero-page (as it comes after E820). As, EDDBUF is not used by boot loaders, this patch should not have any effect on bootloader-setup code interface. Patch covers both i386 and x86-64. Tested on: * grub booting bzImage * lilo booting bzImage with EDID info enabled * pxeboot of bzImage Side-effect: bss increases by ~ 2K and init.data increases by ~7.5K on all systems, due to increase in size of static arrays.

Most of the other changes are modifications in the comments to make kernel-doc happy, accept some parameters description and do not bail out on errors. Changed to @pid in the description, moved some #ifdef before comments to correct function to comments bindings, etc. You can see result of the modified documentation build at http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz Some more sources are ready to be included into kernel-doc generated documentation. Sources has been added into kernel-api for now. Some more section names added and probably some more chaos introduced as result of quick cleanup work.

Similar work-alike -chips from Lite-On, Macronics, ASIX, Compex and other listed below are also -supported. - - - -These chips are used on at least 140 unique PCI board designs. The great -number of chips and board designs supported is the reason for the -driver size and complexity. Almost of the increasing complexity is in the -board configuration and media selection code. There is very little -increasing in the operational critical path length. - - - - - Board-specific Settings - - -PCI bus devices are configured by the system at boot time, so no jumpers -need to be set on the board. The system BIOS preferably should assign the -PCI INTA signal to an otherwise unused system IRQ line. - - - -Some boards have EEPROMs tables with default media entry. The factory default -is usually "autoselect". This should only be overridden when using -transceiver connections without link beat e.g. 10base2 or AUI, or (rarely!) -for forcing full-duplex when used with old link partners that do not do -autonegotiation. - - - - - Driver Operation - -Ring buffers - - -The Tulip can use either ring buffers or lists of Tx and Rx descriptors. -This driver uses statically allocated rings of Rx and Tx descriptors, set at -compile time by RX/TX_RING_SIZE. This version of the driver allocates skbuffs -for the Rx ring buffers at open() time and passes the skb->data field to the -Tulip as receive data buffers. When an incoming frame is less than -RX_COPYBREAK bytes long, a fresh skbuff is allocated and the frame is -copied to the new skbuff. When the incoming frame is larger, the skbuff is -passed directly up the protocol stack and replaced by a newly allocated -skbuff. - - - -The RX_COPYBREAK value is chosen to trade-off the memory wasted by -using a full-sized skbuff for small frames vs. the copying costs of larger -frames. For small frames the copying cost is negligible (esp. considering -that we are pre-loading the cache with immediately useful header -information). For large frames the copying cost is non-trivial, and the -larger copy might flush the cache of useful data. A subtle aspect of this -choice is that the Tulip only receives into longword aligned buffers, thus -the IP header at offset 14 isn't longword aligned for further processing. -Copied frames are put into the new skbuff at an offset of "+2", thus copying -has the beneficial effect of aligning the IP header and preloading the -cache. - - - - -Synchronization - -The driver runs as two independent, single-threaded flows of control. One -is the send-packet routine, which enforces single-threaded use by the -dev->tbusy flag. The other thread is the interrupt handler, which is single -threaded by the hardware and other software. - - - -The send packet thread has partial control over the Tx ring and 'dev->tbusy' -flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next -queue slot is empty, it clears the tbusy flag when finished otherwise it sets -the 'tp->tx_full' flag. - - - -The interrupt handler has exclusive control over the Rx ring and records stats -from the Tx ring. (The Tx-done interrupt can't be selectively turned off, so -we can't avoid the interrupt overhead by having the Tx routine reap the Tx -stats.) After reaping the stats, it marks the queue entry as empty by setting -the 'base' to zero. Iff the 'tp->tx_full' flag is set, it clears both the -tx_full and tbusy flags. - - - - - - - - Errata - - -The old DEC databooks were light on details. -The 21040 databook claims that CSR13, CSR14, and CSR15 should each be the last -register of the set CSR12-15 written. Hmmm, now how is that possible? - - - -The DEC SROM format is very badly designed not precisely defined, leading to -part of the media selection junkheap below. Some boards do not have EEPROM -media tables and need to be patched up. Worse, other boards use the DEC -design kit media table when it isn't correct for their board. - - - -We cannot use MII interrupts because there is no defined GPIO pin to attach -them.

When a change is checked in, all modified files are grouped -into a logical unit, the changeset. Internally, BK links these -changesets in a tree, representing various converging and diverging -lines of development. These changesets are the bread and butter of -the BK system. - -After the concept of changesets, the next thing you need to get used -to is having multiple copies of source trees lying around. This -really- -takes some getting used to, for some people. Separate source trees -are the means in BitKeeper by which you delineate parallel lines -of development, both minor and major. What would be branches in -CVS become separate source trees, or "clones" in BitKeeper [heh, -or Star Wars] terminology. - -Clones and changesets are the tools from which most of the power of -BitKeeper is derived. As mentioned earlier, each clone has a parent, -the tree used as the source when the new clone was created. In a -CVS-like setup, the parent would be a remote server on the Internet, -and the child is your local clone of that tree. - -Once you have established a common baseline between two source trees -- -a common parent -- then you can merge changesets between those two -trees with ease. Merging changes into a tree is called a "pull", and -is analagous to 'cvs update'. A pull downloads all the changesets in -the remote tree you do not have, and merges them. Sending changes in -one tree to another tree is called a "push". Push sends all changes -in the local tree the remote does not yet have, and merges them. - -From these concepts come some initial command examples: - -1) bk clone -q http://linux.bkbits.net/linux-2.5 linus-2.5 -Download a 2.5 stock kernel tree, naming it "linus-2.5" in the local dir. -The "-q" disables listing every single file as it is downloaded. - -2) bk clone -ql linus-2.5 alpha-2.5 -Create a separate source tree for the Alpha AXP architecture. -The "-l" uses hard links instead of copying data, since both trees are -on the local disk. You can also replace the above with "bk lclone -q ..." - -You only clone a tree -once-. After cloning the tree lives a long time -on disk, being updating by pushes and pulls. - -3) cd alpha-2.5 ; bk pull http://gkernel.bkbits.net/alpha-2.5 -Download changes in "alpha-2.5" repository which are not present -in the local repository, and merge them into the source tree. - -4) bk -r co -q -Because every tree is a repository, files must be checked out before -they will be in their standard places in the source tree. - -5) bk vi fs/inode.c # example change... - bk citool # checkin, using X tool - bk push bk://gkernel@bkbits.net/alpha-2.5 # upload change -Typical example of a BK sequence that would replace the analagous CVS -situation, - vi fs/inode.c - cvs commit - -As this is just supposed to be a quick BK intro, for more in-depth -tutorials, live working demos, and docs, see http://www.bitkeeper.com/ - - - -BK and Kernel Development Workflow ----------------------------------- -Currently the latest 2.5 tree is available via "bk clone $URL" -and "bk pull $URL" at http://linux.bkbits.net/linux-2.5 -This should change in a few weeks to a kernel.org URL. - - -A big part of using BitKeeper is organizing the various trees you have -on your local disk, and organizing the flow of changes among those -trees, and remote trees. If one were to graph the relationships between -a desired BK setup, you are likely to see a few-many-few graph, like -this: - - linux-2.5 - | - merge-to-linus-2.5 - / | | - / | | - vm-hacks bugfixes filesys personal-hacks - \ | | / - \ | | / - \ | | / - testing-and-validation - -Since a "bk push" sends all changes not in the target tree, and -since a "bk pull" receives all changes not in the source tree, you want -to make sure you are only pushing specific changes to the desired tree, -not all changes from "peer parent" trees. For example, pushing a change -from the testing-and-validation tree would probably be a bad idea, -because it will push all changes from vm-hacks, bugfixes, filesys, and -personal-hacks trees into the target tree. - -One would typically work on only one "theme" at a time, either -vm-hacks or bugfixes or filesys, keeping those changes isolated in -their own tree during development, and only merge the isolated with -other changes when going upstream (to Linus or other maintainers) or -downstream (to your "union" trees, like testing-and-validation above). - -It should be noted that some of this separation is not just recommended -practice, it's actually [for now] -enforced- by BitKeeper. BitKeeper -requires that changesets maintain a certain order, which is the reason -that "bk push" sends all local changesets the remote doesn't have. This -separation may look like a lot of wasted disk space at first, but it -helps when two unrelated changes may "pollute" the same area of code, or -don't follow the same pace of development, or any other of the standard -reasons why one creates a development branch. - -Small development branches (clones) will appear and disappear: - - -------- A --------- B --------- C --------- D ------- - \ / - -----short-term devel branch----- - -While long-term branches will parallel a tree (or trees), with period -merge points. In this first example, we pull from a tree (pulls, -"\") periodically, such as what occurs when tracking changes in a -vendor tree, never pushing changes back up the line: - - -------- A --------- B --------- C --------- D ------- - \ \ \ - ----long-term devel branch----------------- - -And then a more common case in Linux kernel development, a long term -branch with periodic merges back into the tree (pushes, "/"): - - -------- A --------- B --------- C --------- D ------- - \ \ / \ - ----long-term devel branch----------------- - - - - - -Submitting Changes to Linus ---------------------------- -There's a bit of an art, or style, of submitting changes to Linus. -Since Linus's tree is now (you might say) fully integrated into the -distributed BitKeeper system, there are several prerequisites to -properly submitting a BitKeeper change. All these prereq's are just -general cleanliness of BK usage, so as people become experts at BK, feel -free to optimize this process further (assuming Linus agrees, of -course). - - - -0) Make sure your tree was originally cloned from the linux-2.5 tree -created by Linus. If your tree does not have this as its ancestor, it -is impossible to reliably exchange changesets. - - - -1) Pay attention to your commit text. The commit message that -accompanies each changeset you submit will live on forever in history, -and is used by Linus to accurately summarize the changes in each -pre-patch. Remember that there is no context, so - "fix for new scheduler changes" -would be too vague, but - "fix mips64 arch for new scheduler switch_to(), TIF_xxx semantics" -would be much better. - -You can and should use the command "bk comment -C" to update the -commit text, and improve it after the fact. This is very useful for -development: poor, quick descriptions during development, which get -cleaned up using "bk comment" before issuing the "bk push" to submit the -changes. - - - -2) Include an Internet-available URL for Linus to pull from, such as - - Pull from: http://gkernel.bkbits.net/net-drivers-2.5 - - - -3) Include a summary and "diffstat -p1" of each changeset that will be -downloaded, when Linus issues a "bk pull". The author auto-generates -these summaries using "bk changes -L ", to obtain a listing -of all the pending-to-send changesets, and their commit messages. - -It is important to show Linus what he will be downloading when he issues -a "bk pull", to reduce the time required to sift the changes once they -are downloaded to Linus's local machine. - -IMPORTANT NOTE: One of the features of BK is that your repository does -not have to be up to date, in order for Linus to receive your changes. -It is considered a courtesy to keep your repository fairly recent, to -lessen any potential merge work Linus may need to do. - - -4) Split up your changes. Each maintainer<->Linus situation is likely -to be slightly different here, so take this just as general advice. The -author splits up changes according to "themes" when merging with Linus. -Simultaneous pushes from local development go to special trees which -exist solely to house changes "queued" for Linus. Example of the trees: - - net-drivers-2.5 -- on-going net driver maintenance - vm-2.5 -- VM-related changes - fs-2.5 -- filesystem-related changes - -Linus then has much more freedom for pulling changes. He could (for -example) issue a "bk pull" on vm-2.5 and fs-2.5 trees, to merge their -changes, but hold off net-drivers-2.5 because of a change that needs -more discussion. - -Other maintainers may find that a single linus-pull-from tree is -adequate for passing BK changesets to him. - - - -Frequently Answered Questions ------------------------------ -1) How do I change the e-mail address shown in the changelog? -A. When you run "bk citool" or "bk commit", set environment - variables BK_USER and BK_HOST to the desired username - and host/domain name. - - -2) How do I use tags / get a diff between two kernel versions? -A. Pass the tags Linus uses to 'bk export'. - -ChangeSets are in a forward-progressing order, so it's pretty easy -to get a snapshot starting and ending at any two points in time. -Linus puts tags on each release and pre-release, so you could use -these two examples: - - bk export -tpatch -hdu -rv2.5.4,v2.5.5 | less - # creates patch-2.5.5 essentially - bk export -tpatch -du -rv2.5.5-pre1,v2.5.5 | less - # changes from pre1 to final - -A tag is just an alias for a specific changeset... and since changesets -are ordered, a tag is thus a marker for a specific point in time (or -specific state of the tree). - - -3) Is there an easy way to generate One Big Patch versus mainline, - for my long-lived kernel branch? -A. Yes. This requires BK 3.x, though. - - bk export -tpatch -r`bk repogca bk://linux.bkbits.net/linux-2.5`,+ - diff --git a/Documentation/BK-usage/bk-make-sum b/Documentation/BK-usage/bk-make-sum deleted file mode 100755 index 58ca46a..0000000 --- a/Documentation/BK-usage/bk-make-sum +++ /dev/null @@ -1,34 +0,0 @@ -#!/bin/sh -e -# DIR=$HOME/BK/axp-2.5 -# cd $DIR - -LINUS_REPO=$1 -DIRBASE=`basename $PWD` - -{ -cat </dev/null - -cat < (:D: :I:)\n$each(:C:){ (:C:)\n}\n}' - - -} > /tmp/linus.txt - -cat < 13/02/2002 -# -# Add diffstat output after Changelog 21/02/2002 - -PROG=bksend - -usage() { - echo "usage: $PROG -r" - echo -e "\twhere is of the form '1.23', '1.23..', '1.23..1.27'," - echo -e "\tor '+' to indicate the most recent revision" - - exit 1 -} - -case $1 in --r) REV=$2; shift ;; --r*) REV=`echo $1 | sed 's/^-r//'` ;; -*) echo "$PROG: no revision given, you probably don't want that";; -esac - -[ -z "$REV" ] && usage - -echo "You can import this changeset into BK by piping this whole message to:" -echo "'| bk receive [path to repository]' or apply the patch as usual." - -SEP="\n===================================================================\n\n" -echo -e $SEP -env PAGER=/bin/cat bk changes -r$REV -echo -bk export -tpatch -du -h -r$REV | diffstat -echo; echo -bk export -tpatch -du -h -r$REV -echo -e $SEP -bk send -wgzip_uu -r$REV - diff --git a/Documentation/BK-usage/bz64wrap b/Documentation/BK-usage/bz64wrap deleted file mode 100755 index be78087..0000000 --- a/Documentation/BK-usage/bz64wrap +++ /dev/null @@ -1,41 +0,0 @@ -#!/bin/sh - -# bz64wrap - the sending side of a bzip2 | base64 stream -# Andreas Dilger Jan 2002 - - -PATH=$PATH:/usr/bin:/usr/local/bin:/usr/freeware/bin - -# A program to generate base64 encoding on stdout -BASE64_ENCODE="uuencode -m /dev/stdout" -BASE64_BEGIN= -BASE64_END= - -BZIP=NO -BASE64=NO - -# Test if we have the bzip program installed -bzip2 -c /dev/null > /dev/null 2>&1 && BZIP=YES - -# Test if uuencode can handle the -m (MIME) encoding option -$BASE64_ENCODE < /dev/null > /dev/null 2>&1 && BASE64=YES - -if [ $BASE64 = NO ]; then - BASE64_ENCODE=mimencode - BASE64_BEGIN="begin-base64 644 -" - BASE64_END="====" - - $BASE64_ENCODE < /dev/null > /dev/null 2>&1 && BASE64=YES -fi - -if [ $BZIP = NO -o $BASE64 = NO ]; then - echo "$0: can't use bz64 encoding: bzip2=$BZIP, $BASE64_ENCODE=$BASE64" - exit 1 -fi - -# Sadly, mimencode does not appear to have good "begin" and "end" markers -# like uuencode does, and it is picky about getting the right start/end of -# the base64 stream, so we handle this internally. -echo "$BASE64_BEGIN" -bzip2 -9 | $BASE64_ENCODE -echo "$BASE64_END" diff --git a/Documentation/BK-usage/cpcset b/Documentation/BK-usage/cpcset deleted file mode 100755 index b8faca9..0000000 --- a/Documentation/BK-usage/cpcset +++ /dev/null @@ -1,36 +0,0 @@ -#!/bin/sh -# -# Purpose: Copy changeset patch and description from one -# repository to another, unrelated one. -# -# usage: cpcset [revision] [from-repository] [to-repository] -# - -REV=$1 -FROM=$2 -TO=$3 -TMPF=/tmp/cpcset.$$ - -rm -f $TMPF* - -CWD_SAVE=`pwd` -cd $FROM -bk changes -r$REV | \ - grep -v '^ChangeSet' | \ - sed -e 's/^ //g' > $TMPF.log - -USERHOST=`bk changes -r$REV | grep '^ChangeSet' | awk '{print $4}'` -export BK_USER=`echo $USERHOST | awk '-F@' '{print $1}'` -export BK_HOST=`echo $USERHOST | awk '-F@' '{print $2}'` - -bk export -tpatch -hdu -r$REV > $TMPF.patch && \ -cd $CWD_SAVE && \ -cd $TO && \ -bk import -tpatch -CFR -y"`cat $TMPF.log`" $TMPF.patch . && \ -bk commit -y"`cat $TMPF.log`" - -rm -f $TMPF* - -echo changeset $REV copied. -echo "" - diff --git a/Documentation/BK-usage/cset-to-linus b/Documentation/BK-usage/cset-to-linus deleted file mode 100755 index d28a96f..0000000 --- a/Documentation/BK-usage/cset-to-linus +++ /dev/null @@ -1,49 +0,0 @@ -#!/usr/bin/perl -w - -use strict; - -my ($lhs, $rev, $tmp, $rhs, $s); -my @cset_text = (); -my @pipe_text = (); -my $have_cset = 0; - -while (<>) { - next if /^---/; - - if (($lhs, $tmp, $rhs) = (/^(ChangeSet\@)([^,]+)(, .*)$/)) { - &cset_rev if ($have_cset); - - $rev = $tmp; - $have_cset = 1; - - push(@cset_text, $_); - } - - elsif ($have_cset) { - push(@cset_text, $_); - } -} -&cset_rev if ($have_cset); -exit(0); - - -sub cset_rev { - my $empty_cset = 0; - - open PIPE, "bk export -tpatch -hdu -r $rev | diffstat -p1 2>/dev/null |" or die; - while ($s = ) { - $empty_cset = 1 if ($s =~ /0 files changed/); - push(@pipe_text, $s); - } - close(PIPE); - - if (!
